Semiclassical rotation dynamics of rigid rotors — •Birthe Papendell, Benjamin A. Stickler, and Klaus Hornberger — Fakultät für Physik, Universität Duisburg-Essen

Recent progress in the optical manipulation [1,2] of levitated nanoparticles and the prospect of cooling them into their ro-translational ground state [3] open the door for rotational quantum experiments with nanoscale objects [4]. However, calculating the exact rotational quantum dynamics of such particles is numerically intractable due to the high number of involved rotation states. Here, we present semiclassical approximation methods for planar and linear rotors with several thousand occupied angular momentum states revolving in the presence of an external potential.
